NAME
dwarf_fde_cfa_offset - add a DW_CFA_offset frame instruction to a DWARF
frame descriptor
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_P_Fde
dwarf_fde_cfa_offset(Dwarf_P_Fde fde, Dwarf_Unsigned reg,
Dwarf_Signed offset, Dwarf_Error *err);
DESCRIPTION
Function dwarf_fde_cfa_offset() appends a DW_CFA_offset frame instruction
to the frame descriptor referenced by argument fde.
Argument fde should reference a frame descriptor allocated using
dwarf_new_fde(3).
Argument reg specifies the register operand for the frame instruction.
Argument offset specifies the offset operand for the frame instruction.
If argument err is not NULL, it will be used to store error information
in case of an error.
RETURN VALUES
On success, function dwarf_fde_cfa_offset() returns the frame descriptor
given in argument fde. In case of an error, function
dwarf_fde_cfa_offset() returns DW_DLV_BADADDR and sets the argument err.
ERRORS
Function dwarf_fde_cfa_offset() can fail with:
[DW_DLE_ARGUMENT] Argument fde was NULL.
[DW_DLE_MEMORY] An out of memory condition was encountered during the
execution of the function.
